So I just had my injectors (all of them) and a brand new engine wiring harness installed by Vitale at PitStop in Phoenix about 2 months ago. The car idles perfect now which it didn't do when it was misfiring, and very strong which I like! BUT, for some reason, upon starting it, sometimes it takes a second twist of the key to get it firing. It happens about 50% of the time with no rhyme or reason. Sometimes it fires right up on first crank, and sometimes I have to crank it for 2 or 3 seconds and still no fire until the second twist. I replaced the fuel filter and Iridium spark plugs about a year ago. Could it be my starter or fuel pump?? Any thoughts would be great. Thanks!
